From a connection of mine who is working at a major university in research.
It is clear to me that it is the vaccine and the spike protein as the gene encoding the spike and vector it rides on is directly injected systemically, freely circulating to all tissues and organs of the body. There some particles absorb by the myocardium where it produces spike proteins inside the cardiac muscle tissue, which in turn, spike proteins are lodged and cannot escape which causes inflammation through some undiscovered mechanism contributing to myocarditis. The heart then cannot effectively function and these high level athletes collapse due lack of oxygenation to cardiac tissues or cardiac infarction.
